I'm over 70. A lot of new technology is over my head. And by the way I don't consider pointing out that fact as prejudice. It is very common for people of my age to have not kept up. We simply have other things we care about. Like our grandkids. However, if you enjoy being offended by every little word that doesn't fit your world and life view, go ahead. But if you decide to go that route, expect to have a real crappy life.You should be offended against any type of prejudice. Steve Jobs would be 66 right now, Bill Gates is what - 65?
Clearly not everyone has the same skills - but to imply that someone could not because of their age is offensive.
